The primetime television soap opera “Dallas” is heading back into production on its second season, which has been renewed for a 15 episode run by TNT. The casting directors in Los Angeles are auditioning for two new series regulars – one is a blonde female in her early 20s and the other is a Hispanic male in his early-mid 30s. Additional guest starring and recurring roles will be cast in L.A., while smaller speaking roles will be handled by the Texas casting director. All of the extras are cast in Texas, where shooting will begin on September 24, 2012.
